Knife gate valve is with replaceable rubber seal knife gate structure, its sealing principle is
mainly by closely connection between gate and rubber seals. Its main characters is that the rubber sealing
ring is set in seat’groove and is locked by metal seat, which will prevent rubber seal off when opening
and closing the valve. If the seal is broken, you can remove the metal sear and replace the rubber seal,
which will greatly improve valve’ working efficiency. This valve is a cost-effective, high-performance
products. The series of knife gate valve can be equipped with pneumatic actuators, in order to meet the
requirements of different industrial and mining use.
